FAA warns airline passengers not to use Samsung smartphone

U.S. aviation safety officials took the extraordinary step late Thursday of warning airline passengers not to turn on or charge a new-model Samsung smartphone during flights following numerous reports of the devices catching fire.

The Federal Aviation Administration also warned passengers not to put the Galaxy Note 7 phones in their checked bags, citing "recent incidents and concerns raised by Samsung" about the devices. It is extremely unusual for the FAA to warn passengers about a specific product.

Last week, Samsung ordered a global recall of the jumbo phones after its investigation of explosion reports found the rechargeable batteries were at fault. In one case, a family in St. Petersburg, Florida, reported a Galaxy Note 7 phone left charging in their Jeep caught fire, destroying the vehicle.

Samsung launched the latest version of the Note series in August. The Note series is one of the most expensive lineups released by Samsung, and the devices usually inherit designs and features of the Galaxy S phones that debut in the spring. Samsung also added an iris scanner to the Note 7, which detects patterns in users' eyes to unlock the phone.

Before the issue of battery explosions emerged, supplies were not keeping up with higher-than-expected demand for the smartphone.

The Note 7 isn't the only gadget to catch fire thanks to lithium-battery problems, which have afflicted everything from laptops to Tesla cars to Boeing's 787 jetliner.
